v0.99.3 2002-11-26  Timo Sirainen <tss@iki.fi>

	- mail_read_mmaped = no (default) caused mbox corruption with EXPUNGE.
	  mmap()ing is forced for now.

v0.99.2 2002-11-26  Timo Sirainen <tss@iki.fi>

	+ If we have to wait for a lock longer, the client is now notified
	  about it every 30 seconds.
	- Default settings still pointed to lib directory instead of the
	  libexec directory where the binaries were actually installed
	- vpopmail support had to be kludged to fix a bug in vpopmail library
	  which sometimes left extra character after the user name.
	- Login process crashed if master process didn't let some user login.
	  Normally this couldn't happen without error in configuration.
	- select() based I/O loop wasn't working so Dovecot didn't work in
	  eg. OSX. Also PAM authentication wasn't detected with OSX.
	- Didn't compile with NetBSD-current

v0.99.1 2002-11-25  Timo Sirainen <tss@iki.fi>

	+ Added doc/mkcert.sh script to easily generate yourself a self-signed
	  certificate. Modify doc/dovecot-openssl.cnf before running it.
	+ --with-ssldir configure option to specify default path for /etc/ssl
	+ Added ssl_disable setting to config file
	- OpenSSL wasn't checked properly by configure
	- vpopmail authentication module didn't compile
	- We should install the binaries into libexec dir, not lib
	- doc/configuration.txt and doc/mail-storages.txt were missing

v0.99.0 2002-11-24  Timo Sirainen <tss@iki.fi>

	+ Replaced hash file with binary tree file which makes Dovecot stay
	  fast with large mailboxes after expunging multiple mails.
	+ Several speed improvements with SEARCH
	+ SEARCH CHARSET support using iconv(), although case-insensitive
	  searching is currently supported only for ASCII characters.
	+ OpenSSL support.
	+ Support for regenerating Diffie Hellman and RSA parameters with
	  specified intervals. NOTE: currently doesn't work with OpenSSL.
	+ Support for each login connection being handled in it's own process.
	  This is the default as it's more safe especially with SSL.
	+ mbox locking is now safe, other processes can't modify the mbox file
	  while we're reading it.
	+ Notify clients with "EXISTS" almost immediately after new mail is
	  received.
	+ Rawlog: Support for saving user connections into files - useful for
	  debugging.
	+ Content-Language is finally parsed correctly
	+ Lots of smaller speed optimizations
	- Partial BODY[] fetches weren't working properly
	- BODY[section] was buggy with message/rfc822 MIME parts
	- STARTTLS wasn't working
	- \* flag was missing from PERMANENTFLAGS.
	- Comments inside <> mail addresses crashed.
	- imap-login printed UTC timestamps to logfiles
	- passwd-file wasn't reread the the file changed
	- PAM authentication was implemented wrong, which caused it to break
	  with some PAM plugins.
	- Lots of smaller fixes, mostly to do with reliability

v0.98.4 2002-10-06  Timo Sirainen <tss@iki.fi>

	* Just a final release before replacing hash file with a binary tree.

	- When fetching messages larger than 256k, sometimes Dovecot missed
	  to send CR causing corrupted data at end of message and possibly
	  complete failure depending on IMAP client.
	- Fetching BODY or BODYSTRUCTURE for message having content-type of
	  message/rfc822 didn't correctly add () around the envelope data.
	- Several fixes to make it compile with HP/UX ANSI C compiler.
	  Also fixed several warnings it showed up.

v0.98.3 2002-10-01  Timo Sirainen <tss@iki.fi>

	* Sorry, just noticed a very stupid bug which caused evolution 1.2
	  beta to crash. I always thought it was just evolution's fault :)
	- Several fields in BODY / BODYSTRUCTURE replies weren't quoted

v0.98.2 2002-09-30  Timo Sirainen <tss@iki.fi>

	+ --with-file-offset-size=32 can now be used to select 32bit file
	  offsets. Using them should be a bit faster and take a bit less
	  disk and memory (also needed to compile Dovecot successfully with
	  TinyCC).
	+ maildir_copy_with_hardlinks option works now
	+ Check new mail and notify about it to client also after
	  commands which don't allow full syncing (FETCH, STORE, SEARCH).
	  Also always send RECENT after EXISTS notify.
	+ If we're out of disk space while opening mailbox, notify about it
	  with ALERT.
	- STORE and SEARCH didn't handle properly message sequence numbers
	  when some in the middle were externally deleted
	- SEARCH: Only first search condition was checked.
	- mbox: Message flags given to APPEND were ignored.
	- mbox: index was corrupted when changing flags for multipart MIME
	  messages
	- Out of disk space-handling wasn't working properly with .customflags
	  file
	- if auth processes were killed, login processes weren't reconnecting
	  to them

v0.98.1 2002-09-24  Timo Sirainen <tss@iki.fi>

	+ Faster and safer mbox rewriting when flags are updated
	- Didn't save messages larger then 8192 bytes
	- Several mbox breakages

v0.98 2002-09-23  Timo Sirainen <tss@iki.fi>

	+ mbox support is finally working. There's still some reliability
	  fixes left but overall it should be quite usable.
	+ vpopmail authentication support
	+ We should be able to deal with "out of diskspace/quota" conditions
	  properly, by keeping the indexes in memory and allowing user to
	  delete mails to get more space.
	+ Several speed enhancements
	+ New configuration file option: overwrite_incompatible_index to force
	  using ".imap.index" file, overwriting it if it isn't compatible
	- Handle invalid message headers reliably
	- Tons of bugfixes and code cleanups everywhere

v0.97 2002-08-29  Timo Sirainen <tss@iki.fi>

	+ Large mails are handled in 256kB blocks, so mail size no longer
	  has hardly any effect on memory usage
	+ 64bit file offsets are used if supported by system. This means
	  Dovecot is fully capable of handling >2G mails in those systems.
	  With 32bit offsets >2G mails may not behave too well, but should
	  not crash either.
	+ I fixed lots of potential integer overflows. This should make us
	  fully crash-free no matter what happens (index file corruption
	  mostly). I didn't verify everything too carefully yet, so more
	  auditing is still needed before we fully reach that goal.
	+ Implemented several missing tasks / optimizations to index handling.
	  It should now stay fast after longer usage periods.
	+ New configuration file options: log_path, log_timestamp, imaps_listen
	+ "Critical errors" are now hidden from users, ie. any error message
	  that is not a direct reply to user error is written into log file
	  and user gets only "Internal error [timestamp]".
	+ Nonblocking SSL handshaking
	+ Lots of code cleanups
	- Lots of mbox fixes, it seems to be somewhat reliable now
	- Year in Date-field was parsed wrong
	- Appending mail to mbox didn't work right
	- Always verify that mailbox names are valid (especially they shouldn't
	  contain "../")

v0.96 2002-08-08  Timo Sirainen <tss@iki.fi>

	* Changed to LGPL v2.1 license

	+ STARTTLS support and optional disabling of plaintext authentication
	  (LOGINDISABLED capability)
	+ Support for custom message flags, each folder can have 26 different.
	+ New configuration file options: imap_listen, max_logging_users,
	  max_imap_processes
	+ You can specify config file location to imap-master with -c <path>
	+ All IMAP processes can now write to specified log file instead of
	  syslog. Either do this by setting IMAP_LOGFILE environment, or
	  give -l <path> parameter to imap-master.
	+ Some cleanups to remove warnings with BSDs
	+ Changed all %s .. strerror(errno) -> %m
	+ Rewritten memory pool code
	- imap-master didn't close all the fds for executed processes
	- iobuffer code was buggy and caused the connection to terminate
	  sometimes
	- make install overwrote the existing dovecot.conf file, so it's now
	  named as dovecot-example.conf

v0.95 2002-07-31  Timo Sirainen <tss@iki.fi>

	+ Initial SSL support using GNU TLS, tested with v0.5.1.
	  TLS support is still missing.
	+ Digest-MD5 authentication method
	+ passwd-file authentication backend
	+ Code cleanups
	- Found several bugs from mempool and ioloop code, now we should
	  be stable? :)
	- A few corrections for long header field handling

v0.94 2002-07-29  Timo Sirainen <tss@iki.fi>

	* Supports running completely non-root now. imap-auth however is a
	  bit problematic as we don't support passwd-file yet.
	- Memory alignment fixes mostly
	- Other misc. bugfixes
